HEUSTON H. HOBERT, OF ATLANTIC, ASSIGNOR, BY DIRECT AND MESNEASSIGNMENTS, IOWA.

OF ONE-HALF TO JOHN T. HANNA, OF CASS COUNTY:

- ESCAPEIVIENT FOR MOTORS.

SPECIFICATION forming part of Letters Patent No. 252,581, dated January17, 188.2.

Application filed July 23, 1881. (N model.)

To all whom it may concern Be it known that I, HEUSToN H. HOBERT, ofAtlantic, in the county of Cass and State of Iowa, have invented certainImprovements in Mechanical Powers for Driving Various Forms ofMachinery; and I hereby declare the following to be a full, clear,aud'exact description thereof, reference being had to theaccompanying'drawings, makingpart of this specifi- [o cation, in which-Figure 1 is a front elevation, showing my improved mechanical movementattached to a reciprocating rod for operating a pump. Figs. 2, 3, and 4are details to be referred to. Fig.

5 is a detached view of the escapement.

The object of my invention is to utilize a clockwork mechanism havingany of the usual powers applied to driving such machin ery as willdisarrange or destroy any of the well-known escapelnents now in use,owing to the rough and irregular strains exerted.

My invention consists in the construction of a novel escapeinent forgoverning the power applied to the driving mechanism, as hereinafterdescribed and specifically claimed.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out, forpurposes of illustration showing 0 it attached to a reciprocatingpump-rod.

In the said drawings, Ais a frame, in which are journaled thecog-wheelsB O D of a train of gearing, the wheel B being in thisinstance provided with a spindle, a, containing a wind- 5 ing-drum, b,and an engaging pawl and ratchet, d 6, whereby the cord or chainsustaining a weight is wound 'up to the spindle in order that itsgravity may operate the mechanism. The spindle of wheel D is provided onits end 40 with a crauk,f, which reciprocates the rod g to work a pump,or for any other desired purpose.

Below the main driving-wheel O, and meshing with it, is a pinion, E, onajournal, h. On

5 the samejournal is a cog-wheel, F, of a diameter slightly'larger thancog wheel or pinion E, and on a journal, 11, in the same plane withjournal h, is a cog wheel, G, of the same dimensions with wheel F andmeshing with it.

On the faces of wheels F G,.near their outer edges, and equidistantaround the circumferences, are inserted four pins,p p, on each wheel.The teeth are meshed so that one pin on each wheel alternately passesthrough the plane of the axes ofthe wheels F z,

In a central line between "i 'heels F G, and below them, there is swungon a spindle, t, a pendulum-bar, I, the upper end of which has its sidesrecessed,as shown atn n, and projecting up in the line of travel of theteeth or pins pp, so that when the pendulum-bar I is in a perpendicularposition one of the pins is always in front of one of the recesses a n.The curvature of the recessesiz n is irregular, the shorter curve beingin the lower portion, and the whole of the curve being eccentric to theline of travel of the pins p during the rotation of the wheels F G. Theupper end of the pondulum is curved, as shown at 0. This constructionenables the upper end of the peudu- 7o him, through the medium of thecurved surfaces a a, to come in contact alternately with the pins p onalternate wheels as they revolve. This makes the pendulum-bar I and itssuspended weight K alternately release first a pin on one wheel and thena pin on the other as the pins actuated. by the wheels F G revolve, thecurvature of the upper end of the pendulam-bar being such that as onepin-moves it out of its path it is thrown into the path of theapproaching pin on the other wheel, which in turn throws it back. Thisoperation is aided by the oscillation of the pendulum K.

It is obvious that my invention can be used in a great variety of ways,where a train of actuatcd gearing is used to convey a constantlyappliedpower, and act as an escapement or governor, without departing from itsspirit.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 0 Patent, iS-

In combination with a tiain of gear-wheels, the wheels F G, providedwith the pins pp, and the pendulum-bar I, having its upper end recessed,substantially in the manner set forth, 5 whereby an escapement isprovided, for the purpose specified.

HEUSTON H. HOBERT.
